THE IVORY GULL. 



Pagophila eburnp:a (Phipps). 



The first recorded British specimen of this truly Arctic Gull was 

 obtained by the late Dr. Lawrence Edmonston during the winter of 

 1822, in the Shetland Islands, where this species has subsequently 

 been met with on several occasions. Four examples have been re- 

 corded from the Orkneys, one of them as late in spring as May ; 

 while the Outer Hebrides, Sutherland, Caithness, Banffshire and 

 Aberdeenshire, and even Roxburghshire have been visited, and six or 

 seven birds have been killed in south-western waters, chiefly off the 

 Firth of Clyde. In England this Gull is, naturally, more frequent in 

 the north than in the south ; but its migrations have extended to 

 the Channel and Cornwall, and, exceptionally to Wales ; while in 

 Ireland two birds have been taken and others have been observed. 

 Altogether it may be considered that about thirty-five specimens 

 have been procured in the British Islands, and, of these, rather more 

 than half appear to have been adults.
